LTSpice: Plotting two different simulation traces in one plot

[mc172]

I've got a simulation in LTSpice and what I want to do is plot the output if R10 for example is 10k and also when it is 11k, on the same graph at the same time. Does anyone know if this is possible please?

I'm not doing a tolerance study so don't need to do Monte Carlo analysis, just trying to demonstrate what happens to the output when values change or a variable resistor is adjusted one way or another for example.

Thanks.

Hi,

Use the .step command like this:

.step param Rvalue LIST 10K 11K

replace the value of the resistor you want to change with:

{Rvalue}

Nothing special about the name Rvalue, the names have to be the same.

The simulation will run as many times as you have values.

Easy. Make copy of whole circuit, in same project. Modify value of resistor in 2nd copy.

Spot on. Thanks guys.
